About the Ingredients

Ground Beef (or Beef + Pork Blend)

This is the heart of our meatloaf, providing a juicy, flavorful base that holds everything together.

Small Onion

Finely diced, this ingredient adds a subtle sweetness and aromatic depth to the meat mixture.

Breadcrumbs (or Crushed Crackers)

These not only bind the meatloaf but also contribute to a tender texture that melts in your mouth.

Large Egg

The egg acts as a binding agent, ensuring that our meatloaf stays moist and cohesive while baking.

Shredded Cheddar Cheese

This classic cheese brings a rich, sharp flavor that elevates our mac and cheese to new heights.

Shredded Mozzarella Cheese

Known for its gooey texture, mozzarella adds a delightful creaminess that makes every bite irresistible.

Tips & Tricks

Prep Ahead

Assemble the casserole a day in advance and refrigerate; just pop it in the oven when you're ready to eat!

Don’t Overmix

When combining the meatloaf ingredients, mix gently to keep it tender and avoid a dense texture.

Custom Cheese Blend

Feel free to mix different types of cheese for the topping, like gouda or pepper jack for an extra kick!

Check for Doneness

Use a meat thermometer; the internal temperature should reach 160°F (70°C) for safe consumption.

Pro Tips

  • Use Fresh Ingredients: Freshly grated cheese melts better and tastes more flavorful than pre-shredded varieties.
  • Layer Generously: Don’t skimp on the cheese layer; generous amounts create that comforting, gooey texture.
  • Rest Before Serving: Let the casserole rest for a few minutes after baking to allow the flavors to meld.
  • Garnish Creatively: Add fresh herbs like parsley or chives on top before serving for a pop of color.

Step-by-Step Instructions

Preheat Your Oven

Set your oven to 375°F (190°C) and grease a 9x13-inch baking dish to prepare for that bubbling goodness!

Prepare the Meatloaf Base

In a bowl, mix together the ground beef, onion, breadcrumbs, egg, ketchup, Worcestershire sauce, garlic powder, oregano, salt, and pepper. Press the mixture evenly into the baking dish.

Cook the Macaroni

Bring a large pot of salted water to a boil, add the macaroni, and cook until al dente, about 6-7 minutes. Drain and set aside, letting the pasta cool slightly.

Create the Cheesy Sauce

Melt butter in a saucepan over medium heat, whisk in flour, and cook for about a minute. Gradually add milk, whisking until thickened (about 3-4 minutes), then stir in the cheddar, mozzarella, mustard powder, salt, and pepper until smooth.

Assemble and Bake

Spread the mac and cheese over the meatloaf base and top with additional cheese or crispy onions if desired. Bake for 25-30 minutes until bubbly and golden. Let it rest for 5 minutes before digging in!

Delicious Variations

Spicy Kick

Add diced jalapeños or a dash of hot sauce to the cheese sauce for a spicy twist that will warm you up!

Veggie Lovers

Incorporate finely chopped vegetables like bell peppers or spinach into the meatloaf for added nutrition and flavor.

BBQ Flavor

Mix in some barbecue sauce with the meatloaf for a smoky, tangy flavor that pairs perfectly with the creamy macaroni.

How to Store Mac and Cheese Meatloaf Casserole

Refrigerator

Store leftovers in an airtight container in the refrigerator for up to 3-4 days.

Freeze portions in a freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating.

Frequently Asked Questions

Can I use ground turkey instead of beef?

Yes, ground turkey is a great alternative for a leaner option and works well in this recipe.

What can I substitute for breadcrumbs?

Crushed crackers, panko, or even oats can be used as an alternative binder in the meatloaf.

Can I make this dish vegetarian?

Absolutely! Substitute the meat with a plant-based meat alternative and use vegetable broth in the cheese sauce.

How do I prevent the mac and cheese from drying out?

Ensure there’s enough cheese and sauce in the mixture, and cover with foil during baking if needed to retain moisture.
